If I add multiple axes to a chart, they are all displayed. How can I hide some of the axes? E.g. I want to show project costs 1. against date 2. against working hours Regards Andi

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.
