Refreshing charts in mobile.
Question

Hi guys. I'm trying to implement 3 charts and they depend on values that are selected in three dropdowns. The problem i'm facing is that in p10 I dont have a refresh component(mobile dev), so after I re-execute the action to append the values to the data point I dont know how to refresh the chart on the screen.. Is there anyway to do this?

Hi Paulo,

Just to make sure you're developing a mobile app (rather than a web responsive app), right?

In that case you don't have to refresh anything, the platform will do that for you. When a UI component depends on some data that changed it will re-render automatically. If that's not happening make sure that the charts react to data changes. Which charts component are you using?

I added the action that generates the chart to the charts handler and it worked!

Hi Paulo,


I am struggling to get my charts to update. When you say: "I added the action that generates the chart to the charts handler", what exactly did you mean? Which charts handler? I am creating a mobile app and I am using the regular Charts Mobile charts (line chart). It is not updating when I recreate the datapoints.

I used the action that creates the charts in one of the changes in the screen.. I'll see if I still have access to the project and tell you how exactly, but it was not the perfect solution the screen was really slow to render

It's not true for the Height property, isn't it? I'm calculating the variable on a combobox change, the chart gets updated, but not it's height.

As far as I can ascertain, the Outsystems documented way to update a graph block in a Mobile App does not work: when I change the parameters of a Data Action that generates new datapoints (a parameter of the graph block), the graph does not update. I have tried it with the graph directly in a screen or the graph in a 'Child' block with an "On Parameters Changed" handler: none of them work. I'll see if I can support to look at it.

Hi Dennis, 

I am facing the same problem. 

Did you manage to resolve your issue? 

Thanks, 

Nicholas
