Graph Analysis Tool Graph Screen Operations
4. Move the trace pointer to the end point of the range for which you want to perform
quadratic regression, and then press w.
This displays the quadratic regression calculation
result screen.
5. Press 6(DRAW).
This draws a quadratic regression graph and
overlays it over the original graph.
To delete the overlaid quadratic regression graph,
press !4(SKETCH) and then 1(Cls).
k Overlaying a Y=f(x) Graph on a Sampled Result Graph
You can use the E-CON4 mode to graph equations based on the form Y=f(x). From the
graph screen, press K5(Y=fx) to display the graph relation list screen. From there,
operations are identical to those in the Graph mode.
Note
The data on the graph relation list screen is shared with the Graph mode. Note, however,
that only Y= type graphs can be used in the E-CON4 mode. Because of this, calling up
the graph relation list screen from the E-CON4 mode will display a “Y” (Y= type) item for
function menu key 3. Also, 5(MODIFY) is not displayed, because it is not used in the
E-CON4 mode.
k Working with Multiple Graphs (Not included on the Manual Sampling)
The procedures in this section explain how you can zoom or move a particular graph when
there are multiple graphs on the display.
• To zoom a particular graph on a multi-graph display
1. When the graph screen contains multiple graphs, press K, and then 3(EDIT).
The EDIT menu appears at the bottom of the display.
