Annotations on touch devices

[natasha-f]

It seems that the touch event on mobile devices is not firing. If I select one of the annotation menu buttons, and tap anywhere on the chart area, the chart either does not do anything, or interprets it as a zooming event. I was able to trigger the expected event only in about 10% of testing.
Is it possible to fix this?
Thanks!

@pawelfus Any idea if this will be fixed in near future?

See my answer in the topic above:

The main problem is how annotations.js works: you need to drag&drop to add an annotation, which on touch devices can be interpreted as slide event. We need to add code which will check this (probably Highcharts library has such event, that's why annotation-buttons don't prevent this).

Anyway, I'm more curious about precision of adding annotations on touch devices. Wouldn't be better to disable buttons in such cases?

In short: we need to add new events logic for touch devices, we don't have ETA for this right now. I'm still curious about precision for such annotations..

Precision shouldn't be a problem. To get a feel how it should be, you can see MetaTrader app on iOS/Android and go to Chart section and then draw annotations there.

Any news on this issue?

Can you let us know if you are working on this issue?

[pawelfus]

We will certainly add this functionality, most probably after refactoring events and annotations. Let me connect this to Annotations 2.0 milestone.

Thanks a lot. It would really help if could give an approximate time.

@vrindha - my apologies for a delay in answering. Unfortunately, we don't have any strict date for Annotations 2.0. I hope it will be done in Q4 2016.
