oks or Trend -

Maybe you could use the several instances of the TREND array-entered
function in an adjacent column.

For example, for use one TREND in C1:C10 for the XY data in A1:B10, use
another TREND in C11:C20 for the XY data in A11:B20, etc.

Then use Chart | Source Data | Series to add the new fitted values to the XY
chart.

Hey!

I want to plot trendlines in a xy-chart, not just one. How can I plot
trendlines(linear) in the chart with different steps? Ex for x: 0-100,
100-200...I need the equation of the line of best fit for the different
steps.
