Hi Andi,
I am afraid there is no such property using which one can hide the axes. But it can be done indirectly as discussed below:
To hide Secondary axes: Remove and add from the collection.
To hide Primary axes: Disable the Primary axis labels and change the axis color to transparent.
I have attached a sample which can hide and show the PrimaryXAxis and Secondary X Axis.
F40628.zip
Please implement this and let me know if this helps you.
Thanks for your interest in Syncfusion products.
Regards,
Geetha

Hi Geetha,
thanks for the reply. What I need to display are two curves with the same y-values but not the same x-values. (E.g. costs against time and working hors) I don''t show the curves at the same time.
My idea was to create two series and two axes with different titles and scales.
If the user chooses the curve, I hide the curve and axis that is not needed.
Now I implemented an extra class that holds the points of the curves. When the user chooses, I copy the desired points into the series. (See attachment)
Not a nice solution, because as the curves get large, I shovel around a lot of data. Do you have a better idea?
Regards
Andi
P.S.: I tried to send you a 12kb .zip file, but the server complains: "
Only .zip files under 2MB may be attached to a post"
I just changed the example you gave me.

Hi Andi,
We regret for the delayed response.
Please try calling this.chartControl1.BeginUpdate(); and this.chartControl1.EndUpdate(); before and after adding the series respectively. This will let you to render the large number of points faster.
I hope this helps you.
Please let me know if you have any questions.
Thanks and Regards,
Geetha.
