This page attempts to demonstrate/test many of the possible combinations of various parameters of the ChartPlugin. There are too many combinations of parameters to test all possible combinations, so only a few are shown here.

 |
combo tests
Simple combo graph using table #2. Since no datatype is defined and only a single data set, combo defaults to a single line. |
 |
| Change so 3 data sets are drawn as areas and the last drawn as a line |
 |
| Same as above, adding grid lines and both X and Y axis labels and titles |
 |
Same as above adding subtype="area" which should force all data sets to be drawn as area. Since the last data set would fall behind the previously drawn areas, it is drawn as a line |
 |
Same as above changing subtype="line" which should force all data sets to be drawn as line |
 |
Same as above changing subtype="bar" which should force all data sets to be drawn as bar |
 |
Same as above changing subtype="pline" which should force all data sets to be drawn as pline |
 |
Same as above changing subtype="point" which should force all data sets to be drawn as point |
 |
Same as above changing subtype="area line pline point" |
 |
Same as above changing subtype="line pline point area" |
 |
Same as above changing subtype="pline pline point bar" |
 |
Same as above changing subtype="area pline point bar". This should produce an error as you can't combine area and bar subtypes |
ChartPlugin error: chart error: name=combo_12: Error: Can't mix 'area' and 'bar' subtypes on the same chart |
scatter tests
Simple scatter graph using table #3. Defaults to all data sets drawn as point |
 |
| Same as above, adding title, grid lines and both X and Y axis labels and titles |
 |
Same as above adding subtype="line" |
 |
Same as above changing subtype="pline" |
 |
Same as above changing subtype="point" |
 |
Same as above changing subtype="bar" |
 |
Same as above changing subtype="point bar line pline" |
 |
Same as above changing subtype="bar line pline point" |
 |
Same as above changing subtype="line pline point bar" |
 |
Same as above changing subtype="pline point bar line" |
 |
Same as above changing subtype="bar bar bar pline" |
 |
Same as above changing subtype="area pline point bar". This should produce an error as you can't combine area and bar subtypes |
ChartPlugin error: chart error: name=scatter_12: Error: Can't mix 'area' and 'bar' subtypes on the same chart |
New functionality tests
Test various legend placement situations
| Test that when all lines overlap on the very bottom of the chart, the legends all show up non-overlapped |
 |
| Test that when two lines overlap in the middle of the chart, the legends get correctly placed |
 |
| Similar to the test above, except the data is changed such that the placement of the legends for the two middle lines should be reversed |
 |
| Test that when 4 lines are close to overlapping and are all located at the top of the chart, the legends get correctly placed. |
 |
| Test that when 4 lines do exactly overlap at the top of the chart, the legends get correctly placed. |
 |
| Test that the arrangement of legends of 4 lines located at the top of a chart is correct. |
 |
Test that even with a ymax set too low such that the lines go off the top of the chart, the legends still stay on the chart. |
 |
Test that even with a ymin set too high such that some lines do not even show up on the chart because they fall below the chart, the legends still stay on the chart. |
 |
Test extremes that even when ymin is set higher than all data, that the legends still get drawn on the chart. |
 |
Test extremes that even when ymax is set lower than all data, that the legends still get drawn on the chart. |
 |
Test numxgrids and xaxisangle options
| Show what happens when there is so much data that the X axis labels overlap |
 |
Take the above graph and specify numxgrids = "3" making the X axis labels more readable |
 |
Take the first graph and specify xaxisangle = 90, changing the X axis label angle = 90 degrees |
 |
Test scale and ytics options
Show how scale=semilog makes the chart easier to read. Since ytics is NOT specified, it defaults to 8. |
 |
Show the above plotted data on a linear scale with ytics=1 |
 |
Test defaultdata option
Show what happens when there is sparse data. defaultdata = 0 |
 |
Same as above, but now defaultdata = 10 |
 |
Same as above, but now defaultdata = "none" (empty) |
 |
Test gridcolor option
| Show default grid color with solid grid lines. |
 |
| Change the grid color to blue. |
 |
| Change the grid color back to the default but make them dotted |
 |
| Change the grid style to be 5 black dots and 5 transparent dots. |
 |
| Change the grid style to be 4 red dots, 4 green dots, 4 blue dots and 4 transparent dots. |
 |
| Change the grid style to be 1 black dot which basically makes a solid line |
 |
