Chart Zoom out other than mouse wheels

[Sriram]

Is there a way to zoom out charts other than using mouse wheels? I want to zoom out on double click on the area/range/line chart. How can i do that?

Hello, Sriram,

I already provided an answer to this in the ticket.

I will share the code here, so more people can benefit from it:

We monitor both the support tickets and the forum threads. Please avoid posting duplicate threads at both places, as it can lead to overhead in our support department. Thank you for understanding.

I dont think the solution you have provided is acceptable. You are just defaulting all the options on double click. What if i need some of the options to persist? For example, i have n number of plot bands drawn in the chart. The moment i double click and sets the default options, all my plot bands are also gone. Any other suggestion you have?

Hello, Das,

Thank you for the feedback.

As this is not supported out of the box, I just provided some approach which can be used and modified depending on the need.

In the case where the options have to be preserved, all of the options should be passed on the setOptions method in order to set completely the same options.

I hope this is helpful.

Hi Stefan,

Thanks for your quick response. Can you please let me know how can i just hold the plot bands that are there in my chart when calling setOptions to zoom out?

Hello, Das,

If the plotBands are part of the categoryAxis configuration, then the categoryAxis configuration should be passed to the setOptions method.

I modify the example to demonstrate this:

If this is not the case, please share an example of the real scenario, so I could provide an approach best suited for it.
