plot

Dear team,
I want a plot where two variables are plotted on the X and Y axis whereas the third variable can be plotted on the Z axis. An example plot is attached here. Can I get a graph like this?

Thanks and regards,

If your data are stored in a 2D histogram h2 use:

h2->Draw("colz");

If your data are stored in array use TScatter.

Thank you for your response.
My data are stored in an array. So, I am trying to use TScatter. But I got an error like this
"error: unknown type name ‘TScatter’ "

What should I do?

Thanks and regards,
Arpita

We can use TScatter for version 6.30. But I have Root version-6.22.
Is there any easy way to update my Root version from 6.22 to 6.30?
I need to complete the plot. So if you can help me it will be great.

Thanks and regards,
Arpita
