 3D Column Chart |

Hello,
Im looking for a way to create a 3D column Chart (see picture). The nearest chart type which I found is the scattered surface chart or 3D scattered group.
Any ideas ...
Lars

Hi Lars,
Yes. The "Depth Bar Chart" is an example:
https://www.advsofteng.com/doc/cdnet.htm#depthbar.htm
In the above example, the bars are tightly packed in the "depth" dimension. In your attached image, there is some gaps between bars in the "depth" dimension. In ChartDirector, the gap can be configured using the Layer.set3D API.
As I am not sure of your programming langauge, I will just use C#/Java as an example:
BarLayer layer0 = c->addBarLayer(barDataArray0, barColor0, layerName0);
layer0->setBorderColor(Chart.SameAsMainColor); // no border color
layer0->set3D(10, 5); // 10 pixels 3D depth, plus 5 pixels 3D gap
BarLayer layer1 = c->addBarLayer(barDataArray1, barColor1, layerName1);
layer1->setBorderColor(Chart.SameAsMainColor); // no border color
layer1->set3D(10, 5); // 10 pixels 3D depth, plus 5 pixels 3D gap
.... repeat for other layers ....
In practice, instead of repeating the code for other layers, you can use a loop to add all the layers, as the code are all the same. Only the data/color/name are different.
Hope this can help.

Hi Peter,
Thx for the answer and the test code. I will try this out with Perl.
