bar with diagonal lines pattern chart

Hi all

I need to create a bar chart where it will be filled with lines inside. The diagonal white lines has alternating with bands of another color chosen dynamically.

I know we have itemrenderers and we can use it.

I was able to fill the full bar with a picture

But not able to reach the exact needs.

Pls help...

Hi Marco,.

Use of the component below as an itemRenderer for your histogram, you will reach the desired output, you need.

package components.renderers
{
import flash.display.Graphics;
Import mx.charts.series.items.ColumnSeriesItem;
Import mx.core.IDataRenderer;
Import mx.core.UIComponent;
 
SerializableAttribute public class BarColorItemRenderer extends UIComponent implements IDataRenderer
{
public static const colors: Array = [0 x 000000, 0 X 938953, 0X1F497D, 0XC0504D, 0X9BBB59, 0X8064A2, 0X4BACC6, 0XF79646, 0X7F7F7F, 0X548DD 4, 0 X 632423, 0X4F6128, 0XB2A2C7, 0X31859B, 0 X 974806, 0X20B2AA, 0XF5DEB3, 0XDDA0DD, 0XE9967A, 0X7FFFD 4];
private var _chartItem: *;
    
public void BarColorItemRenderer () {}
Empty constructor.
}

public function get data (): object {}
Return _chartItem;
}

public function set {data(value:Object):void}
If (ColumnSeriesItem)
{
_chartItem = value as ColumnSeriesItem.
}
invalidateDisplayList();
}
override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void {}
super.updateDisplayList (unscaledWidth, unscaledHeight);
var Graphics = g:Graphics;
g.Clear ();
g.beginFill (colors [(_chartItem == null)? 0:_chartItem.index]);
g.drawRect (0, 0, unscaledWidth, unscaledHeight);
g.lineStyle(2,0XFFFFFF,1);
var barY: int = 10;
var moveX:int = 10;
moveY var: int = 0;
var stripWidth:int = 10;
While (barY< unscaledheight="" ||="" movey=""><>
{
g.moveTo (moveX, moveY);
g.lineTo(0,barY);
  
If ((moveX + stripWidth)<>
{
moveX += stripWidth
}
on the other
{
moveX = unscaledWidth;
moveY += stripWidth.
}
barY += stripWidth.
}
g.endFill ();
}
}
}

Thank you

  • After the FrameMaker is imported in RoboHelp, some items/styles appear in boxes with diagonal lines

    I have a chapter in FrameMaker which does not convert on RoboHelp correctly. The text and images in this section appear inside the rectangular boxes with diagonal lines. When I compile the Help menu, this section is oblique with the curiously resized images and large spaces where they do not belong. I guess that these boxes with the average of the diagonal lines something obvious and hope someone can share what this might indicate the error?

    I thought that maybe he had some problems in the structure of the FM model that is the source, but it seems in good condition. Curiously, all the other sections in the same chapter are created in a manner identical outputs without problem.

    Thanks in advance,

    Hello

    The diagonal lines are probably conditional build tags. Do you have the conditional tags in FrameMaker? If so, the conditional tag HR is also conditional on FM. For your problem else Jeff may have even more ideas. Also try searching the forum for problems of framemaker and image. There was a couple of posts on this topic in recent months.

  • How to create the variable diagonal line pattern in CS6?

    Hi guys

    I'm at the edge of madness with the creation of my pattern of diagonal lines. I've tried everything I can think of, but the boss is an absolute mess! I want to create a pattern of diagonal lines, but I want the lines to not be uniform. Basically, I had a group of 3 lines and then a separate line on its own, then repeating this like the image below. I used the function of distributing the distances between the lines is the same everywhere. I then turned the all exactly 45 degrees and aligned with the lines to fit in the bounding box in the mode 'as the motive"as shown. Yet, the resulting model is just a mess of the ugliness of overlap. Can all that I want is the model literally watch as it does in the picture on the left, someone you please tell me how to sucessfully this in CS6? Would be eternally grateful!

    Desired design: pattern problem.png result:ugly pattern.png

    Never create a line pattern obliquely. It is not necessary.

    Create the model at 90 ° angle and then use object > transform > Rotate and check the option "Transform Patterns" and enter the angle you are after...

    Try to get the slanted lines to match a pattern can take a lot of effort. Where as with this method you can create the pattern and turn it in a few minutes. Let the Illustrator to work for you rather than against you. And, you can rotate to any angle, so the model will work in many ways.

  • Windows Vista crashes, the screen becomes pink with diagonal dotted lines

    My HP Pavilion DV9500 laptop started making a few months ago:

    The computer and the programs sometimes simply freeze, sometimes the screen becomes a light pink with diagonal lines dotted, and sometimes the laptop itself restarts without warning.  The computer is about 3 years old now and have not had any problems before this.  I tried to do a clean install of the recovery feature that I don't have a Vista disc to reinstall from, and he always does this.  Sometimes the computer will be fine for a few hours and sometimes just after the start it will freeze.  A couple of times too, as it starts, Windows will not start and it will say "Not found operating system".

  • How do a diagonal lines filling?

    I want to fill a simple box of diagonal lines. How to make a fill with different widths of line style?

    Ok. So what you want to do is to create a fill pattern. I'll try my best to explain it in terms of cs5 as bosses have changed since then.

    You must first create the lines. Draw two vertical lines high to 1 "ETV 1" out. Select the two lines, and then click object > blend > make. After mixing, click object > blend > mix Options. Check the "Preview" in the lower left. Click the menu drop-down (I believe the default is "smooth color"). Select "specified steps" and enter the values in the dialog box until the lines look appropriate on the other distance. When you are finished, click ok.

    Select the blend object, and then click object > break down. In the dialog box, make sure that only the "Subject" box is selected. Click on expand.

    at this point, you have a group of selected vertical lines. Rotate 45 group * draw a rectangle around the outer edges of diagonal lines.

    now that scale down so that the whole box is inside the diagonal lines.

    Select the two objects, and then click object > clipping mask > make

    duplicate this object and keep it on the side (because if you need to adjust the width of the line in the future, you will need this). now select the original one and go to your Pathfinder palette and click 'crop '. This gets rid of the clipping mask, so you're left with diagonal lines extended.

    Now drag the object extended/cropped in your Swatches Panel and voila. don't forget to name the new filling of model so that you can identify it (you do not want to have several different models, called 'New model Swatch 1' and 'new shade of motif 2 "etc. etc..)

    If you need to adjust the width of the outline for a different reason, see the duplicate what you did before and isolate the traits to adjust the width of the line and repeat the above steps to crop.

  • How to choose if a specific item in a combination chart is a bar or a line? Help

    Hi all

    I use JDeveloper 12 c.

    I've created a combination chart where I chose the name and FkStore as x-axis and I selected 4 data points (amount, AmountPlanned, margin, MarginPlanned) and I wanted to only two of these elements bar and the other two lines.

    Although I can make two data points bars and a single line, the last of them is a region of the element type and I wanted to 2 bars and 2 lines.

    Is this possible to do? How can I choose what type of element I want for each attribute? I though it might be on the definition page but had no luck there.

    Here is a picture of how the element is at the moment: https://www.dropbox.com/s/z3a8746vtbc8sx0/Frederico.png

    As you can see, the amount is not a bar, and I wish it were.

    Here is the code for the graph:

    < dvt:comboGraph id = "chart" 6

    value = "#{bindings." AVG_Sales_Geral1.graphModel}.

    Subtype = "COMBINATION_VERT_ABS".

    shortDesc = "barLineGraphAVG."

    styleClass = "AFStretchWidth."

    inlineStyle = "width: 700px; height: 400px; ">

    < name dvt:attributeFormat = "AvgMargin".

    ID = 'af11' >

    < af:convertNumber pattern = "#{bindings." AVG_Sales_Geral1.hints.AvgMargin.format}.

    groupingUsed = "false" / >

    < / dvt:attributeFormat >

    If you have an idea, I would appreciate it.

    Kind regards

    Hi Frederico,

    For each series, you can specify the type of marker you want using the dvt:series tag.

  • Pattern of diagonal lines that remains unchanged

    Hey guys, meet another problem. I need to make a template - filling of diagonal lines that go to the length of the object in its entirety, but keep the distance to 3 px between them (vertically), and they do not change their rotation or scale of the object when I change it (I know about the option scale for models). I tried to get the model, but when I apply it to a square I get the misalignment of the fill lines, and they rotate as well with the rectangle. Thank you!

    Ok

    1 draw the line at 45 degrees, expand stroke.

    2 transform and create copies on 10

    3 Expand apearance

    4. then create a square (no line) with the corners in this position

    lines like this and pathfinder divide still separate and remove all parts that were outside the square.

    5 should now look like this

    6 then group and drag in the color chart

    its all about cutting the right place...

I suspect it was the thing to restore default setting that worked at one point. (I'm definitely NOT a geek as you might have guessed.)
