We will show the sense of the memory menus on the basis of an example. It is similar to example 1.

Let us start with any data in the physical coordinate system (shortly: chart).

The Pulldown-menu <Edit> should look at follows:

Now load a data file from disk. Press key <Control + L>. Select again the file <Gaus.dat> in the sample folder:

Then make an AutoScale in the next dialogbox:

The result looks very simple so:

In the TestMode the previous data are not longer available. They are exchanged against the new ones. Ok, interpolate the SampleData with a Cubic Spline function to show a curve in the chart: Press ALT + A, I  C RETURN or call the menu:

It shows you now the SampleData in form of the marker and the curve in the chart. Both together  (data and curve) are build the current graph!

Next step, switch from TestMode to the EvaluationMode. Call the Pulldown-menu <Edit> menu <Set EvaluationMode>. It shows you the next dialog:

Yes, this is the memory record dialogbox, prepared for data input. It waits on you so that you press on the button <Store>. Please recognize that the <Colour & Style> comes from Default. Let’s do it, press the <Store> button.

So you will see now the chart with its default properties on the screen. Maybe it looks the same as in the TestMode. If you have forgotten to set the hook to the checkbox <CurveData> in the above dialog so you will miss the curve, certainly.

In the Statusbar there is a calculator symbol that can be switched on and off to show you the same in the chart. Switch it on and click on it in the chart. It stays on the current graph to showing you the current memory record.

Click on it to call again the Memory Record Dialogbox.

To avoid boredom repetitions please click the button <Calibrate> in this dialog to call the Calibration dialog. We will multiply the y-Axis with the factor 0.1 to press together the graph in y-direction. Do it with Ok. Afterwards press the button <Store>. You will see this view:

Press again the key <Control + L> to load another data file (e.g. INTERPOL.DAT). Immediately the Memory Record Dialog pops up to store the data manually by you. If you unhook the menu <Auto Set to Memory> you will not longer get this dialog in future because SimplexNumerica stores the data automatically by itself.
