Description of all FlashChart Parameters

News

Release 1.3.4

Code has been reworked and changed to be run with Joomla Version 4. This release has been successfully tested with Joomla Version 4.0 Beta3.
Important! With build-level 1.3.4.1 all media (javascripts, Images, stylesheets) have been moved to
directory "/media/plg_content_flashchart".

Release 1.3.3

All interfaces to Joomla's framework have been changed to implement joomla's V3 php exploitation of PHP-Namespaces.

Release 1.3.2

Release 1.3.2 is an updated version of release 1.3.1. Code changes have been implemented to be able to run with PHP Version 7.

Release 1.3.1

Two new options "target_line" and "target_linecolor" have beeen added. "target_line" lets you display a line for a given value within coordinate system in addition to the grid of your chart. "target_linecolor" sets the color for this target line. If you omit this parameter, "target_linecolor" defaults to "grid_color".

Build Level 1.3.1.2 now supports logarithmic scaling of y-axis with paramerter "log_scaley". Also with this build content of tooltips has been made more consistant when parameter "x_label_truncate" is used.

Release 1.3.0

Code has been completely restructiured and performance improvements have been incorporated.

New in Release 1.2.2

Release 1.2.2 is mainly a "Security-Release" - e.g. in all php-scripts will be checked, wether the Joomla Framework is used. This means that every direct call outsite the framework will fail with an error.

With this release the interface to modal windows has been extended. With parameter "modal_chart", you may now request a chart to be created and displayed in a modal window. This function has been implemented with the bootstrap framework for modal windows.

The OFC Post/Get interface is no longer (for security reasons and limited functionality) supported. In addition exception-handling for database interfaces (MYSQL) has been recoded to support Joomla Version 3.x API.

New in Release 1.2.1

With this release you get a series of improvements and enhancements:

• New chart types - scatter charts:
• scatter_dot
• scatter_star
• scatter_box
• scatter_hollow
• Calculation and display of trend (trend line) for bar charts and line charts
• Regression analysis for scatter charts:
1. linear regression
2. exponential regression (two types)
3. use of own regression formulas
• Creation of chart's data via math formula

New in Release 1.2.0

• Flash-Object ("open-flash-chart.swf") has been reprogrammed and enhanced with new features
• FlashChart supports actions on "mouse click events" (via mouse clicks on chart elements various actions can be invoked and executed).
• Pie charts may now have legends
• Radius of pie charts may be defined instead of using default of OFC
• You may place legends on right side of chart (instead of top of chart)
• You now may create and use chart menues
• fixed problem with horizontal bar charts (type="bar_horizontal") if you have multiple data series
• Data values may be displayed on bar and line charts.
• Added javascripts and functionality to create javascripts to be used for click-events on chart elements or menues
• You may create charts instead of background color now with a background image
• Instead manually rearrange data for stacked bar charts, flashchart can do it for you on request
• Support for "standalone" web applications
• plus some code improvements

Changes

Parameter "c_color" changed to more meaningful name "chart_colors". To activate pls. go to "plugin manager" in your administrator backend and select "FlashChart content plugin", then click "save" to activate new setting.

Hints and Tips

Hints and tips

My Parameters seem to be O.K. but chart does not display or I see an error message
Some problems of this kind are caused by Joomla!'s WYSIWIG editors. I myself saw that some editors were too "smart correcting" my data entry. Blanks had been substituted by " " or tab-chars or special chars like "=" or "/" got replaced by a HTML-Coded character. To analyse these issues look at the html-source with your Editor and correct it if required.

Print Chart
Since build 1.2.0.13 you may print your chart via context menu. Call menu by right clicking into the chart.

Print entire Page
FlashChart gives you the ability to save/convert your charts to images. This also solves the printing problem for browsers other than Microsoft's IE. You only need to convert your displayed charts into images (done with a click) and then printing works same as with IE. Or you can now use your charts as normal images (e.g. copy/paste) when they have been converted to image. Or you may use javascript "print_page" (available with this release).

Notes on the stacked bar charts:
If you are requesting a side by side bar chart every value within a datagroup will create one bar with same color. This behaviour is different with stacked bar charts . Here every value within a datagroup will create one stack with different colors on a single bar.
E.g. if you have data="Jan,Feb,Mar,Apr / 10,20,30,40 | 50,60,70,80" and request type="bar_cylinder" you will see four side by side bar pairs. If you then would request type="bar_stacked" with same data, you would see only two stacked bars resulting in wrong creation of your chart. To correct this you must rearrange the data portion to: data="Jan,Feb,Mar,Apr / 10,50 | 20,60 | 30,70 | 40,80" (if data is coming from database this rearrangment of data is done by flashchart).

With version 1.2.0 you may now rearrange your data via parameter rearrange_data="1" on request instead of doing it manually.

Notes on the mysql interface:
With flashChart you can query data from tables within the Joomla! database or other mysql databases. The creation of your chart depends on data returned from database, and is therefore highly depedant on your entered SQL-statements. The result of your query will be handled by flashChart in a following way:

1. If result contains only one data column from your query or you have set parameter "sql_labels" to "0" data goes directly to your chart
2. If result contains two ore more data columns coming from your query and parameter "sql_labels" is set to "1" (this is the default) then:
   • first column will be used for x-axis labels
   • all other columns will be used for chart-data. Every single column will build a single datagroup (and will be used for creation of side by side bar-charts, stacked bar-charts or multi line-charts).
