The Chart & List Window allows you to graph functions, plot data and
edit lists. You can also use this window to perform numerical calculus.
Press F12 at any time to show or hide (toggle) the Chart & List Window, or select
View->Chart & List from the calculator's main menu.
The Graphing & Professional Editions of DreamCalc provide a two page window with Chart View and List Data
pages, as seen below. The Professional Edition has an additional Cashflow List for use in financial cashflow calculations.
DreamCalc Chart & List Window
The Scientific Edition of DreamCalc does not support graphing and shows only the List Data page for
use in statistical calculations.
Available Charts
The following chart types are supported:
- Function Graph: two functions can be plotted on the same chart.
- X-Y Data Plot: shows a line of best fit for the current regression mode.
- Polar Plot: can be shown for either function graphs or X-Y data.
- Histogram: shows weighted data in SD mode.
- Frequency Polygon: shows weighted data in SD mode.
- Bar Chart: shows either X-Y or SD data.
- Q-Q Plot: normal quantile-quantile plot of SD data*.
*Professional Edition Only.
Graphing a Function
To graph a function, select Chart->Function Graph from the Chart Window's menu. See Graphing a Function for further information.
Plotting X-Y List Data
To plot X-Y data, first put the calculator into a suitable X-Y data mode from the Window's Mode menu.
For example, click Mode->Linear Regression (X-Y).
Next click the Data List page tab and enter your X-Y data (you may copy and paste from a spreadsheet
application or import a file).
Then select a suitable X-Y chart from the Chart menu, i.e. Chart->X-Y Data
Charts->Scatter Points. Additionally, you can elect to show the line of best fit by toggling the
Show Regression Fit menu option.

The example above shows an X-Y scatter plot with a cubic regression fit. You can toggle the statistical
information shown beneath the plot by selecting View->Show Footer.
Plot SD List Data
To display SD data, put the calculator into the Statistical Data mode. Then select a suitable chart, i.e. a
histogram, from the Chart->SD Data Charts menu. Further information is available for Statistical Data Charts.
Logarithmic & Polar Plots
An X-Y style chart can be shown with logarithmic axes, or converted to polar form. Use the Axes menu
to select from the available options. You may select logarithmic scales for x and y axes independently. See also
Polar Plots for further information.
Plot Tracing
You can use your mouse to easily trace along a plot—a circular marker will automatically follow the path of
the plot. The coordinates of the plot tracer are displayed in the lower left of the window (see
below).
Plot Tracing
You can "grab and hold" the current plot tracer position at any time by single clicking on the chart at the
desired location.
Try this...
1. Move the cursor over a plot.
2. Single click at the desired position (do not drag the mouse).
3. Move the cursor away from the chart.
You will now see the coordinates were stored in the position box under the chart. You can click the copy
button to the right of the box to copy the text to the clipboard.
Values are shown to the precision allowed by the size of the chart window. If two plots are visible, the
trace marker will follow the plot nearest to the mouse cursor.
Zooming
You can perform chart zooming by simply dragging a rectangle over an area of interest with the mouse.
To unzoom, click the [UNZOOM] label which will appear at the bottom right of the chart, or select
View->Unzoom.
Exporting Charts
A chart can be saved as one of several commonly used image formats from the window's File menu.
Perhaps the easiest method of export, however, is to simple copy the chart into the clipboard using the
Edit menu. Two copy options are available: copy as metafile or bitmap. The metafile format is ideal for
pasting into documents because it is vector based and can be resized without loss of resolution. However, there
may be instances where only a bitmap is compatible.
