Even after searching Google and triple-checking my radians values, etc. I was still having trouble with this, so I have created a jsFiddle for people to play with as a live example and will post the code below as well. (Update: in the fiddle v2, stroke and labels are added also.) var canvas = document.getElementById(“can”); … Read more
Solution for ChartJs Version > 2.1.5: Chart.pluginService.register({ beforeRender: function (chart) { if (chart.config.options.showAllTooltips) { // create an array of tooltips // we can’t use the chart tooltip because there is only one tooltip per chart chart.pluginTooltips = []; chart.config.data.datasets.forEach(function (dataset, i) { chart.getDatasetMeta(i).data.forEach(function (sector, j) { chart.pluginTooltips.push(new Chart.Tooltip({ _chart: chart.chart, _chartInstance: chart, _data: chart.data, _options: … Read more
You could just set the ylabel by calling pylab.ylabel: pylab.ylabel(”) or pylab.axes().set_ylabel(”) In your example, plt.axes().set_ylabel(”) will not work because you dont have import matplotlib.pyplot as plt in your code, so plt doesn’t exist. Alternatively, the groups.plot command returns the Axes instance, so you could use that to set the ylabel: ax=groups.plot(kind=’pie’, shadow=True) ax.set_ylabel(”)
You can turn off the labels in the chart, and then define them within the call to legend: df[col].plot(kind=’pie’, autopct=”%.2f”, labels=[”,”,”,”], ax=ax, title=col, fontsize=10) ax.legend(loc=3, labels=df.index) or … labels=None …
Just override in this way it will work definitely function tooltipContent(key, y, e, graph) { return ‘<h3>’ + key + ‘</h3>’ +'<p>’ + y + ‘</p>’ ; } Or tooltipContent(function(key, y, e, graph) { return ‘Some String’ })
Just override in this way it will work definitely function tooltipContent(key, y, e, graph) { return ‘<h3>’ + key + ‘</h3>’ +'<p>’ + y + ‘</p>’ ; } Or tooltipContent(function(key, y, e, graph) { return ‘Some String’ })
You can control the distance of the percents and labels from the center of the pie using pctdistance= and labeldistance=, try this on your code: plt.pie(sizes, labels=labels, autopct=”%1.0f%%”, pctdistance=1.1, labeldistance=1.2) You can also set a radius of the pie using radius= (by default is 1)
The simplest way to change the font size on a pie chart is directly via the textprops argument in the pie() function. Using the code above add it like so: ax.pie(frac, colors=colors ,labels=labels, autopct=”%1.1f%%”, textprops={‘fontsize’: 14}) That way you can just pass in a dictionary with your desired fontsize (e.g., 14).

The short answer is: You may use plt.legend‘s arguments loc, bbox_to_anchor and additionally bbox_transform and mode, to position the legend in an axes or figure. The long version: Step 1: Making sure a legend is needed. In many cases no legend is needed at all and the information can be inferred by the context or … Read more
