I want to get position(x,y) of a tick in x-axis of a graph to manual draw a line according it, please help me!
Please view below image to get my clearly question:
You can get the Y coordinate of all x-axis ticks like this:
y = ActiveChart.Axes(xlValue).CrossesAt. In your example image, this will be 0.
The ticks on the x-axis will have X coordinates between
ActiveChart.Axes(xlCategory).MaximumScale, both inclusive, at intervals of
Of course, if you know ahead of time which X value you want to highlight, then that X will be the X coordinate of the tick.
The above is assuming your chart is selected/activated. Instead of
ActiveChart, you can use
ActiveSheet.ChartObjects("Chart 1").Chart or whatever the correct reference to your chart is.
EDIT: Just realized that the example you show is a Line chart. It won’t be possible to do what you’re asking on a Line chart. You have to change the chart type to an XY (Scatter) chart first.
