When feeding altimeter data into an app using mpChartLib it gives this graph
However when I import the data into a csv file it yields
As you can see there is a difference at the bottom.
Anyone an idea what might cause the negative spikes in the mpChartLib graph?
Looking at the tow images it seems that in the first one the points are joint with cubic splines and in the secondone with straight lines.
Meaning cubic lines through the data points, removing the 'knees' in the line ?
This might be a property of the chart.
Example:
Blue: points joined with straight lines.
Red: points joint with cubic splines.
This happen when there are big and steep changes.
