===HeatMapTimeAxis===

The **HeatMapTimeAxis** function of the [[mplreport]] class is similar to the [[TimeAxis]] function, but is used when you don't have a DateTime index to work with.

Given a number of //samples//, it creates axis ticks that look like dates/times.

Note that it assumes that your data is **regularly spaced** - that there is an equal length of time between each sample.

==Parameters==

^Parameter^Type^Default^Meaning^
|axis|Axis||The MatPlotLib axis object to modify.|
|samples|int||The number of samples in your range.|
|starttime|DateTime|None|The start of your time range. If //None//, uses the start of the report range.|
|endtime|DateTime|None|The end of your time range. If //None//, uses the end of the report range.|

==Return==

None

==Example==

<code>
report.TimeAxis(ax.xaxis,200)
</code>

//This creates an x-axis that appears as a date range covering the range of the report, even though the actual x-axis values are between 0 and 200.//
