 Is this type of graph/scaling possible? |

Hello Peter,
Thank you for all your replies to us users.
I have a question for you: is this graph possible to create with Chartdirector? Is the type of scaling? Can we set the scaling parameters ourselves?
Thank you for answering,
Frank

Hi Frank,
Yes. You can use any scale you like. Basically, it is just a kind of labelling the axis, and
ChartDirector allows you to put any label at any position on the axis.
From your attached image, I am not sure the exact formula for your scale. Assume your
scale is defined by a function that maps the data value to a position on the axis, where 0
means the left end of the axis, and 100 means the right end of the axis. As an example,
lets assume the function is position = value * value * 3 + 10
Function myFunction(x)
myFunction = x * x * 3 + 10
End Function
The code is then:
'0 = left end, 100 = right end. Initially no labels
Call c.xAxis().setLinearScale2(0, 100, Array())
'Add the label 1, 2, 3, 4, 5 at the proper position
For i = 1 to 5
Call c.xAxis().addLabel(myFunction(i), i)
Next
When you want to plot a chart, you need to put the points in the proper position to:
For i = 0 To Ubound(myXData)
myXData(i) = myFunction(myXData(i))
Next
Hope this can help.

| Thank you, Peter! We only needed to tweak the function, it works fine. |
