Hello, as some situations, zoom not work please see the folowing exapmle, you cannot zoom anywhere https://jsfiddle.net/QwZuf/2759/

@ukimuzik, The current behavior while zooming is as per design. We will revisit this behavior in our future releases. -- Thangaraj Raman Team CanvasJS

In some situations, this is a restriction which limits the user functionality and does not make sense. E.g. if you are using a range bar chart to display events on a time range and there are e.g. only 2 events within 24 hours (full time range), but the initial viewport is only the last 10 hours: In that situation it should be possible to use the panning functionality to move back to the first event which may actually be outside the viewport (e.g. at the beginning of the 24h range). But due to the restriction you described, panning and zooming is not possible.

@stefan-alfs, We are limiting the zooming & panning to have a minimum of 3-4 datapoints across x-axis in case of xy zooming type. This behaviour is designed to help users not zoom into blank regions (region with no dataPoints). ___________ Adithya Menon, Team CanvasJS

There are already a few JSFiddle examples in this topic which show you the problem. You could also use the range bar chart example, reduce the data to e.g 2 data points and then you should be able to reproduce this.

@elbit12,

We are busy with implementing some important features as of now. Hence, there is no definite timeline.

Hello,
did you fix this bug?

@larry,

The behavior is designed such that zooming is limited upto a certain region, so that user doesn’t end up zooming into a blank-region (region with no dataPoints). To zoom into a certain region, there should be a minimum of 3-4 dataPoints over the axis.

In your case, the zoom doesn’t work as there are less than 3-4 dataPoints with different values over the axisY.

We will reconsider this behavior for future releases.

the problem is not that “there are less than 3-4 dataPoints with different values over the axisY”
see this example:
you can see that axisY is same value and you can zoom
https://jsfiddle.net/26d5Lqcj/

please update me when this bug is going to be fixed because its cause me lots of problems.
and if you found what cause this problem

Thanks

@larry,

In the JSFiddle that you have shared, it’s possible to zoom as the region gets validated since zoomType is set to ‘xy’. In this case, the zoomed region is valid because of number of dataPoints over axisX. And in the previous JSFiddle that has been shared the region is getting invalidated because of axisY.

Can you please explain again?
I didn’t get the difference:
in both examples the zoom type sets to ‘xy’.
in the ‘working’ example ‘x’ values are changed and ‘y’ values has the same value.
in the ‘not working’ example ‘x’ values are changed and ‘y’ values have 2 different values.

if problem is axis y , so why its working when axis y is not changed at all, and not working when axis y has small change?

Thanks,
Larry

Hello,
can you please reply on Larry’s question?

Larry, @elbit12,

The behavior is by design so that zooming is limited upto a certain region, so that user doesn’t end up zooming into a blank-region (region with no dataPoints). To zoom into a certain region, there should be a minimum of 3-4 dataPoints over the axis.

When zoomType is either set to ‘x’ or ‘y’, it checks for number of datapoints over specific axis. But when zoomType is ‘xy’ it checks for the datapoints within the selected region over both the axes because of which it gets invalidated in certain cases. We will reconsider and improve this behavior in future releases.

Hello,

please see the following example:
https://jsfiddle.net/Lzbmgkc7/

there are more than 4 points with different Y value
and there are more than 4 points with different X value

and zoom is still not available

can you please explain this?

@elbit12,

Sorry, for the late response.

please see the following example:
https://jsfiddle.net/Lzbmgkc7/

Thanks for reporting the use-case. As we are working on some important updates, we have not set any definite timeline for the fix.

Can you please brief us further about your exact requirement so that we can suggest any possible workaround to overcome this issue?
