Python Area Charts & Graphs
Python Area Charts are similar on Line Charts with the region between line & the axis base filled with color. Area Charts are generally used to show trend, cumulative sum using numbers or percentages over a period of time. CanvasJS lets you add different variants of Area Charts to your Django app like Area, Multi Series Area, Spline Area, Step Area, Stacked Area & Stacked Area 100% Charts.
To make visualization better, markers are shown for every datapoint only when there are less number of datapoints. Markers get hidden when the data set is large. Library provides option to show markers at specific datapoint, letting you highlight particular datapoint out of a large dataset.
Python Area Charts
Area Charts are useful when you are interested in cumulative totals over a period of time.
Python Spline Area Charts
Spline Area Chart is similar to area chart except that the envelope of area is a smooth curve.
Python Step Area Charts
Step Area charts are drawn by connecting the data points using vertical and horizontal lines and shading the enclosed area.
Python Stacked Area Charts
Stacked Area is formed by stacking multiple data-series of area type one on top of the other.
Features Commonly used in Python Area Charts
Most commonly used features in Python Area Chart includes markers, indexlabels, changing color & opacity of the filled region, etc.
- You can control the envelope’s thickness by setting lineThickness property.
- Size & type of the marker can be set using markerSize & markerType properties.
- Indexlabel can be shown at a particular datapoint by setting indexLabel property in datapoint.
- Color & opacity of the filled region can be changed by setting color & fillOpacity properties.
- You can localize/customize culture specific elements of a chart using decimalSeparator & digitGroupSeparator in culture property of chart.

General Tips for Python Area Charts
- Use Stacked Area Chart when you have multiple data sets and want to emphasize part-to-whole relationships.
- Limit the number of area data series as they tend to overlap each other. You can also use transparency in such cases.
- While combining area with other chart types, keep other types in front of area so that they are not hidden.
