I'm trying to plot population vs. country name and I found that the Google Visualization library is rendering only the first few (actually number is seemingly random depending on the data I use) and sometime add "Other" entry, but it doesn't actually have the value of the rest of the entries.

Example 1: With all countries data With all countries data

Example 2: With some countries filtered out After filtering out some countries

Is there an actual limit on number of rows? Why is it inconsistent? Is there a way to get around it. I know it's difficult to view if I plot population of all countries on a pie chart, but I should at least be able to do it.

My issue that I can't get a hold of the source code so I can't really see what is going on. Anyone has any idea? Worst case, I will have to sort all data and show the ones with highest number of population first, but i really want to avoid doing that.

There's an option for sliceVisibilityThreshold, which would probably solve your problem. It's set to 1/720 by default, which is .5%

I tried opening it up to 1/10000 and it did not solve my problem. It puts the tiny slices on the legend, but it's still not using them to calculate the percentage. That's a real problem because the % is also in the data table (that I'm displaying) where it is correct.

This solved the main part of the issues. The other part was caused by my data source not giving me all rows I expected. I do have the same concern on the calculation as well, but what I do is to leave the smaller slices in "others" slice, which seems to be okay for calculation.

You can set the sliceVisibilityThreshold: equal to 0 to disable it. You should pass it through a options var. 0.00001 > 0

 var options = { title: 'Popularity of Types of Pizza', sliceVisibilityThreshold: 0 }; var chart = new google.visualization.PieChart(document.getElementById('chart_div')); chart.draw(data, options);
