Spreadsheet Graphics and Charts

Graphics can be created using the Graph button in the spreadsheet view or from the sheet listing, which takes the user to tiki-graph_sheet.php?sheetId=1 (1 or the numeric id of that sheet). Two simple forms are presented to select the parameters of the graphic.

Select the Graphic Type and Output Format


Fig. 1: First form

The radio buttons select the type of graphic to be generated. A first example will be made with the Pie Chart and a second one with Multibar. Multiline and Bar Stack use the same parameters as Bar Stack.

Multiple output formats are available. Depending on the installed extensions on the server, some elements might not be available. PDF and PostScript are printable format and require the paper size and orientation parameters. PNG and JPEG are images and require height and width parameters in pizels.

If the objective is to include the graphic in a wiki page, the selected format will only be used for the preview.


Figure 2 presents the parameters entered to obtain a pie chart from the speadsheet and Figure 3 is the result obtained. The page is divided in three sections:

  1. Parameter form
  2. Spreadsheet
  3. Wiki Plug-in

The parameter form is used to select the elements that will be displayed in the graphic. All parameters under the series label are value ranges from the spreadsheet in A1:Z99 format or comma seperated list of elements (ex: Blue, ))LightBlue,LightGreen((). The color and style series require special values:


  • Red
  • Green
  • Blue
  • Yellow
  • Orange
  • LightBlue
  • LightGreen


  • Thin-LineStroke
  • Thin-FillStroke
  • Normal-LineStroke
  • Normal-FillStroke
  • Bold-LineStroke
  • Bold-FillStroke
  • Bolder-LineStroke
  • Bolder-FillStroke

The spreadsheet is available as a reference to select the ranges.

The wiki plug-in is updated as the parameters are changed in the form. The code displayed can be pasted in a wiki page to display the graphic. The plug-in does not consider the selected output format. Instead, it will automatically select the best format available. If possible, it will display an image and link to a printable format. Prefered image format is PNG and prefered printable format is PDF.

Pie Chart Parameters

The following table presents the different field of the form, what they are used for and the behavior if left empty.

Figure 4 presents the parameters used to create the graphic in Figure 5. Note that different size parameters have been used to suite the large amount of data. Here is the table presenting the different parameters.

Title Title of the graphic No title
Independant Scale Determines if the graphic is vertical or horizontal
Horizontal Scale Location of the horizontal scale
Vertical Scale Location of the vertical scale
Label Caption of the different elements in the legend No legend

Style Border type used Normal-FillStroke
X Independant scale range Required.
Y0 First dependant range Required.

Spreadsheet JQ Charts

Another option is to make the charts reusing the raphael.js charting library embedded in the jquery spreadsheet. See:
