Description
The
upper part of this windows shows a list of data sets (chart curves) displayed
in chart window. Use data set's checkbox to show or hide it in chart window.
- Load - you can load a saved chart data
set and display it in chart window. Clicking the button will first bring
up a standard window to browse data set file.
- Save - saves the selected data set to file.
You can Load saved data sets back to chart window and compare them
with other data sets. The figure above shows a chart for Odd/Even numbers
and charts odd_even1 and odd_even2 saved from statistics
data calculated in previous steps.
- Remove - permanently removes the selected
data set from chart window. You can temporarily hide any data sets using
the checkbox in the list.
- Shift minimum by - each data set (curve)
has a minimum and maximum value. The absolute minimum and maximum values
are displayed at the bottom of the chart window. The minimum value of
data set selected in this window is also displayed in the field below
the list. Checking the Shift minimum by option will subtract the
given value from all chart's data sets. This way you can improve the differentiation
of chart's points because the Y axis range will show only the difference
between the maximum and minimum values.
- Custom Grid Colors - opens a new window
where it is possible to define custom colors for different parts of the
chart area. The button is enabled only for charts that allow invoking
of filters from the chart window.
- Chart Color - default color for chart bars
and points. Clicking the button will bring up a standard window for color
selection. If the chart window shows a line chart then the color is used
for data points only, the points are connected with a black line.
- Divider Color - default color for chart
bars and points at highlighted positions (e.g. 10, 20, 30 etc). Clicking
the button will bring up a standard window for color selection. If the
chart window shows a line chart then the color is used for data points
only, the points are connected with a black line.
The
lower part of this window shows controls common for all chart's data sets:
- Bar Chart - shows chart's data sets as
a histogram. Each data point is represented as a bar whose height is defined
by point's value.
- Line Chart - shows chart's data sets as
points connected with a line.
- Show average/optimal value - shows a dashed
red line in the chart window representing the average value. If the chart
window contains more than one data set then the average value is calculated
for the first data set in the list. Hover your mouse pointer above the
line to see its current value. Please remember that the displayed value
is lower than the actual value when the Shift minimum by option
is switched on. E.g. if the average value shows "67" and the
chart's minimum is shifted by 291 then the real average value is the sum
of these two values (358).
- Show range tool - shows in the chart window
two dashed black lines of the range tool. All data points within the selected
range are displayed in brighter colors. You can change the range by dragging
the range lines with your mouse. Hover your mouse pointer above a range
line to see its current value. Please remember that the displayed value
is lower than the actual value when the Shift minimum by option
is switched on.
- Default range +/- % - you can set
the default positions of range tool to the specified percentage of chart's
maximum value.
- Show grid colors - when enabled then
the background of the chart window will be evenly divided into given number
of colored stripes for easier visual evaluation of displayed data.
- Bar width - the width of chart bars (in
pixels).
- Spacing - the distance between chart bars
and also the distance between line chart points.
- Close - closes this window.
Note: Charts available from the Statistics
page contain automatically the following items for the assessed parameter:
- <assessed parameter> - Occurrence; number occurrence is assessed in the
figure above; so the assessed parameter is "Number"
- <assessed parameter> - Latest; interval to the first occurrence of parameter
(number) back in the lottery past.
- <assessed parameter> -Period; average period of occurrence of assessed
parameter (number) in the lottery past.
