 Multi-Bar Chart with Positive and Negative Bars |

Hi Peter,
I am trying to create a Multi-Bar Chart, 2 in my case, with Positive and Negative Bars (best example would be Change in OI for Options Calls and Puts) but can't produce it. I am fetching data from database and using VS 2015. Either Call or Put data is being plot, but not both at a time..!!
Regards

Hi AC,
There are quite a number of "Multi-Bar Chart" examples included in ChartDirector. You can try to modify the data in those examples with negative values. They should still work.
For example, consider:
https://www.advsofteng.com/doc/cdnet.htm#glassmultibar.htm
The data in the above example are:
Dim data0() As Double = {100, 125, 245, 147, 67}
Dim data1() As Double = {85, 156, 179, 211, 123}
Dim data2() As Double = {97, 87, 56, 267, 157}
If you change some of the values to negative, it will still work.
If the above still cannot solve the problem, is it possible to create a simple example with hard coded data to illustrate the problem?
