tick with label at the intersection of the two axes

Post by cssesuc » Wed Oct 21, 2015 9:47 am

dear experts,
As it is illustrated on the attached screen capture, I need to have series with the vertical axis which has a first tick at its intersection with the horizontal axis.
In the attached example, I want to have 1E+9 displayed.
I had a careful look at the different options of the LeftAxis, but failed to come to something which is functional.
How can I force the Chart to display a first tick with label at the intersection of the x-axis and the vertical axis.

Hello Nabil,

You should set the Left axis AutomaticMinimum property to false it then you should be able to set a Minimum for the axis.

If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem here.

Hi,
many thanks for the suggestion. This is indeed what I did in the end, but this was not enough. In addition, I had to fix the minimum value of the LeftAxis, such that the label at the intersection of the horizontal and the vertical axes is displayed. To do this, I simply:
- find the minimum of the series (s_min, s_min is always positive in my case),
- search for the value of n, such that 10^n+1 > s_min >= 10^n,
- fix LeftAxis.Minimum to 10^n

thanks
