How to Show toolbar tip values without clicking bar in bar chart ? about williamchart HOT 11 CLOSED

Thanks for raising the issue, it might help other people.
As I told you before, in the meantime I've added the method ArrayList<Region> getEntriesRegions(int setIndex) (only in DEV branch for the time being) for those cases when you want to place tooltips without necessarily need to get a click event.
From that method you will get all regions matching each entry of a given set and then you're free to build your tooltip the way you want (as I do in the sample application for example).
I hope this answers your question. If not let me know.

Hi, Still i am confusing how to use that in bar chart ?
In updateBarChart() method how to use ArrayList getEntriesRegions(int setIndex) and show the values in bar.Can you please create sample for that ? It will helpful for me.Thanks.

from williamchart.

Have you looked, for example, at the method showBarTooltip in the sample application?
If I understood you correctly you will need something like:

updateBarChart(){
    ...
    chart.show();
    regions = chart.getEntriesRegions(setIndex);
    for(int i = 0; i < regions.size(); i++)
        showTooltip(regions.get(i))
}

private void showTooltip(Rect rect){
    // With the help of ``LayoutParams``you can set the position and size of your tooltip.
    LayoutParams layoutParams = new LayoutParams(rect.width(), rect.height());  
    layoutParams.leftMargin = rect.left;
    layoutParams.topMargin = rect.top;

    // The ``R.layout.tooltip``can take any shape you want (once again, you can see the 
    // tooltip xml examples in the sample application). 
    mBarTooltip = (TextView) getLayoutInflater().inflate(R.layout.tooltip, null);

    // Set the previous configured ``LayoutParams``to the inflated layout.
    mBarTooltip.setLayoutParams(layoutParams);

    // Pass the view to the chart
    chart.showTooltip(mBarTooltip);
}

Hi here is the code based on your suggestion.

ArrayList<ArrayList> regions;
regions = mBarChart.getEntriesRegions(setIndex);
for (int i = 0; i < regions.size(); i++)
showTooltip(regions.get(i));

What's the value for set Index ?

You created private void showTooltip(Rect rect){......} but in the for loop you created showTooltip(regions.get(i)).

from williamchart.

The meaning of setIndex should be also either described in the code or in the Wiki documentation, you should take a look. The setIndex is the index value of your dataset. As an example, in case you only have a dataset in your chart your setIndex will be 0.

Didn't get your last question.

from williamchart.

You created the following method to display tooltip.
private void showTooltip(Rect rect){...}

But inside the for loop you created the following method
showTooltip(region.get(i))

If i put setIndex value 0. I am getting error.

from williamchart.

Inside the loop I haven't created any method, I simply called the method showTooltip(Region).
If you get an error than you're doing something wrong. Remember that you can only call the method getEntriesRegions after you instantiate your chart and show it. Feel free to post your error here.

from williamchart.

Hi, there is no method for getEntriesRegions(set Index) in the chart view class.
Inside the loop you have called showTooltip(Region).You didn't create any method showTooltip(Region).

Where should i call the following method ?

private void showTooltip(Rect rect){
// With the help of LayoutParamsyou can set the position and size of your tooltip.
LayoutParams layoutParams = new LayoutParams(rect.width(), rect.height());
layoutParams.leftMargin = rect.left;
layoutParams.topMargin = rect.top;
// The R.layout.tooltipcan take any shape you want (once again, you can see the
// tooltip xml examples in the sample application).
mBarTooltip = (TextView) getLayoutInflater().inflate(R.layout.tooltip, null);
// Set the previous configured LayoutParamsto the inflated layout.
mBarTooltip.setLayoutParams(layoutParams);
// Pass the view to the chart
chart.showTooltip(mBarTooltip);
}

I am struggling for past 3 days.Please help me Very Thanks..

from williamchart.

Yes there is, I already told you twice that for the time being is only in DEV branch.

What I gave was a draft of code from the top of my head which you should understand, not just simply make a copy/paste. You're are struggling for 3 days and you couldn't figure it out that each Region object has a getBounds() method to return its Rect object? I'm really trying to help you, but you need to understand what you are doing before you actually do it.
