+Charts
+++++++
+
+You can generate some nice charts from your stamps. So far only bar charts
+showing the total time per day can be generated, but you can filter them by
+**ID** and/or date. Some examples:
+
+- Render a chart of all the times already stamped, by **ID**::
+
+    stamps -g
+
+- Render a chart of the stamps for the last 4 days::
+
+    stamps -g 4d
+
+- Render a chart of the stamps for the **ID** *stamper* for the last week::
+
+    stamps -g stamper 1w
+
+.. note::
+
+   The charts will be saved into **~/.workstamps-charts**, in SVG_ format.
+   The name of the chart will be generated based on the current date and
+   time, and a *symbolic link* called **chart-latest.svg** will be created,
+   pointing to the latest chart generated.
