Related to: MPAndroidChart BarChart xValues Issue

English isn't my first language. So, Please excuse me if I'm not so clear, feel free to ask details.

I'm having the same problem as in this post: MPAndroidChart BarChart xValues Issue

In a barchart with 2 series xVals labels aren't displayed correctly, here are some test cases:

case 1

xVals = from 1 (index 0) to 30 (index 29) (days in a month, say april)
set1 = 3 values for 3 days (10,17,22): a.e. barentry(100,10), barentry(200,17), barentry(300,22)  
set2 = 3 values for 3 days (4,11,18): a.e. barentry(100,4), barentry(200,11), barentry(300,18)

in this case the barchart displays bars and xvals labels as independent, any bar is below his xvals label

case 2

xVals = from 1 (index 0) to 30 (index 29) (days in april)  
set1 = as previous but added 0 values with set2 index : a.e. barentry(0,4), barentry(100,10), barentry(0,11),barentry(200,17), barentry(0,18), barentry(300,22)  
set2 = as previous but added 0 values with set1 index : a.e. barentry(100,4), barentry(0,10), barentry(200,11),barentry(0,17), barentry(300,18), barentry(0,22)

in this case the barchart displays bars and xvals labels as independent, any bar is below his xvals label

case 3

xVals = from 1 (index 0) to 30 (index 29) (days in april)  
set1 filled with 0 for everyday barentry(0,[0 to 29]), then added values for 3 days (10,17,22): barentry(0,10)....  
set2 filled with 0 for everyday barentry(0,[0 to 29]), then added values for 3 days (4,11,18): barentry(0,4)....

in this case I can see every bar in the right place with relative xvals label but it's horrible to see all these 0s!

Please take note that if in case 1 I don't add set2 (so a simple barchart with 1 series) everything it's ok without the need 0 values.

The question is: How can I get rid of the 0 values where not needed (as in example in days 1 to 3 and so on)?

Thanks in advance

Edit:
PFA screenshots, both are the same graph the only difference are sets with/without all days value.
The code is same from multidataset example and it works fine for every graph.

Only days with data: http://mysite.altervista.org/temp/some.png

All days: http://mysite.altervista.org/temp/all.png

For getting rid of the zeroes, use the ValueFormatter, and return an empty string whenever the value is zero.

Concerning the issue with the x-labels: I'm not sure what the issue is here.

The chart does only dispalys as many x-values as there is space on the screen. The position of the x-labels depends on their position in the xvalues-array, and is independent from the position of your entries.

If you zoom in, all x-values should appear.
