MBS Chart Director

RicSum · **Posted:** Tue Jun 26, 2012 12:44 pm

Hello,
Can anyone who may be using MonkeyBread's ChartDirector plugin tell me how to:

A) Make all of the bars appear the same colour (as opposed to random colours).

B) Remove the default white background behind the bars.

Thank you all in advance.

Well, if you call addBarLayer, you can pass a color or an array of colors for the bars. If you pass one color all bars have same color. If you pass array, you define the colors for the bars. If array is empty or has not enough values, you get default colors.

With background, you can pass different background color to CDXYChartMBS constructor for whole drawing area or to setPlotArea for plot area.
if you want complete transparent background, please look into the "simplePie with transparent background" example project.

Greetings
Christian

Christian,

OK, I have edited my code below, and now all of my bars are the same colour, but I still have no idea how to change the default color, or how to make then 3d:

dim u,i as integer

dim data(-1) as double
dim labels(-1) as string

u=list.ListCount-1
for i=0 to u
  labels.Append list.Cell(i,0)
  data.Append val(list.cell(i,1))
next

dim c as new CDXYChartMBS(canvas1.Width, canvas1.Height)
dim colors(-1) as integer
colors.Append CDXYChartMBS.RGB(202,225,255)

call c.setPlotArea(30,20, Canvas1.Width-50, canvas1.Height-50)

call c.addBarLayer (data)

call c.xAxis.setLabelS labels

canvas1.Backdrop=c.makeChartPicture

Thanks for trying to help, but I guess I will have to make do with my plain old bars.

Thanks.

See this lines:

dim colors(-1) as integer
colors.Append CDXYChartMBS.RGB(202,225,255)

call c.setPlotArea(30,20, Canvas1.Width-50, canvas1.Height-50)

call c.addBarLayer (data, colors)

How about you change this to.

call c.setPlotArea(30,20, Canvas1.Width-50, canvas1.Height-50)
call c.addBarLayer (data, CDXYChartMBS.RGB(202,225,255))

by removing the array, you don't get the default color palette.

And next, for the glass effect, you could simply go on:

call c.addBarLayer (data, CDXYChartMBS.RGB(202,225,255))

Replace the call with

dim layer as CDBarLayerMBS =

so you have

dim layer as CDBarLayerMBS = c.addBarLayer (data, CDXYChartMBS.RGB(202,225,255))

This way you have the layer object in an extra variable.
So you can run this code

layer.setBorderColor(c.kTransparent, c.glassEffect(c.kNormalGlare,c.kLeft))

For adding glass effect to borders.
First parameter here gives transparent borders and second part adds a glass effect with normal glare and light from left.

Thank you very much Christian - I now have all bars the same color, of which I can now choose.

Is it possible to advise me how to make my bars 3D ?
I can then leave people in peace and study all of the code provided.

I really appreciate all the help - FOR ME, it is soooooo much easier to learn from example code, as I often do not understand general pointers.

Thank you VERY much.

To find out how to make 3D bar, go to the examples for ChartDirector plugin. More than 200 examples, so go in icon mode in Finder/Explorer and look on the thumbnails we have there.
Once you find threedbar.rbp, open it and look inside. There you see:

// Add a bar chart layer with green (0x00ff00) bars using the given data
dim b as CDBarLayerMBS
b=c.addBarLayer(data, &h00ff00)
b.set3D

As you see this example creates bars with a single color (what you asked above).
Now you see a call there with set3D. Add this to your project.

Look here for docs:
http://www.monkeybreadsoftware.net/char ... d.shtml#25

So you see you can pass two parameters here, if you like.
