- RPIECHART

The controls can be integrated into mobile pages and into other pages. The charts are built using the tool chart.js, see http://www.chartjs.org/

## RCHART and RCHARTDATA

The RCHART control supports rendering the following charts:

- line charts

- bar charts

- horizontal bar charts

An RCHART control can have several RCHARTDATA controls as sub controls. Each RCHARTDATA control describes rendering and data for the datasets shown in the chart.

#### Example

Several examples and corresponding description are provided in the Natural for Ajax demos.

#### Properties for RCHART

Basic
rcharttype | Type of the chart. Examples: bar,horizontalBar,line. | Optional | bar horizontalBar line
rcharttypeprop | Name of the adapter parameter that provides as value the type of the chart. Valid values are line, bar, horizontalBar | Optional |
labels | Semicolon separated list. Example: 2015;2016;2017. In a bar chart these are the labels shown for the x-axis. In a horizontal bar chart these are the labels shown for the y-axis. | Optional |
labelstextid | Multi language dependent text that is displayed inside the control. The "textid" is translated into a corresponding string at runtime. Do not specify a "name" inside the control if specifying a "textid". | Optional |
labelsprop | Name of the adapter parameter, which contains the label values. The field is generated as child of the valueprop field. | Optional | label1;label2;label3
valueprop | Name of the adapter parameter that provides the content of the control. | Obligatory |
style | CSS style definition that is directly passed into this control. With the style you can individually influence the rendering of the control. You can specify any style sheet expressions. Examples are: border: 1px solid #FF0000 background-color: #808080 You can combine expressions by appending and separating them with a semicolon. Sometimes it is useful to have a look into the generated HTML code in order to know where direct style definitions are applied. Press right mouse-button in your browser and select the "View source" or "View frame's source" function. | Optional |
styleclasses | CSS style classes separated by a blank. | Optional |
stackedxaxis | If set to true the bars or lines of the chart are stacked on the x-axis. | Optional | true false
stackedyaxis | If set to true the bars or lines of the chart are stacked on the y-axis. | Optional | true false
selectedlabelprop | Name of the adapter parameter to which the value of the selected label is set on click. | Optional |
changeindexprop | Name of the adapter parameter providing a value which indicates whether the control should be refreshed with new data on the client or not. A different value than the previous triggers the refresh. It does not need to be a higher value. | Optional |
showvalueinchart | Show the values in the chart. Per default the values are shown as tooltip. | Optional | true false
showvaluepos | If set to inside the values are shown inside the chart. If set to outside the values are set outside the chart. Default is inside. | Optional | inside outside
showtooltip | If set to false tooltips are disabled. Default is true. | Optional | true false
showvaluefontfamily | The font family which is used to show the value. | Optional |
showvaluefontstyle | The font style which is used to show the value. | Optional |
showvaluefontsize | The font size which is used to show the value. | Optional | 1 2 3 int-value
showvaluefontcolor | Color of the control. Value must follow format "#rrggbb", e.g. #000000 for black. | Optional | #FF0000 #00FF00 #0000FF #FFFFFF #808080 #000000
comment | Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view. | Optional |
BarOptions
xaxisscalelabel | The text for the label of the scale for this axis. | Optional |
xaxisscaletextid | Multi language dependent text that is displayed inside the control. The "textid" is translated into a corresponding string at runtime. Do not specify a "name" inside the control if specifying a "textid". | Optional |
yaxisscalelabel | The text for the label of the scale for this axis. | Optional |
yaxisscaletextid | Multi language dependent text that is displayed inside the control. The "textid" is translated into a corresponding string at runtime. Do not specify a "name" inside the control if specifying a "textid". | Optional |
xaxisbarthickness | Width of the bars in pixels. If not set, the bars are sized automatically. | Optional | 20 30 40 50 60
xaxisbarpercentage | Percent (0-1) of the available width each bar should be within the category percentage. 1.0 will take the whole category width and put the bars right next to each other. | Optional | 0.4 0.5 0.7 0.8 0.9 1.0
xaxiscategorypercentage | Percent (0-1) of the available width (the space between the gridlines for small datasets) for each data-point to use for the bars. | Optional | 0.5 0.6 0.7 0.8 0.9 1.0
yaxisbarthickness | Height of the bar in pixels. If not set, the bars are sized automatically. | Optional | 20 30 40 50 60
LineOptions
showlines | If set to false the line is not drawn for this dataset. | Optional | true false
Miscellaneous
testtoolid | Use this attribute to assign a fixed control identifier that can be later on used within your test tool in order to do the object identification | Optional |
width | Width of the control. There are three possibilities to define the width: (A) You do not define a width at all. In this case the width of the control will either be a default width or - in case of container controls - it will follow the width that is occupied by its content. (B) Pixel sizing: just input a number value (e.g. "100"). (C) Percentage sizing: input a percantage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a width this control can reference. If you specify this control to have a width of 50% then the parent element (e.g. an ITR-row) may itself define a width of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect. | Optional | 100 120 140 160 180 200 50% 100%
height | Height of the control. There are three possibilities to define the height: (A) You do not define a height at all. As consequence the control will be rendered with its default height. If the control is a container control (containing) other controls then the height of the control will follow the height of its content. (B) Pixel sizing: just input a number value (e.g. "20"). (C) Percentage sizing: input a percentage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a height this control can reference. If you specify this control to have a height of 50% then the parent element (e.g. an ITR-row) may itself define a height of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect. | Optional | 100 150 200 250 300 250 400 50% 100%

#### Properties for RCHARTDATA

datatype | By default, the control is managing its content as string. By explicitly setting a datatype you can define that the control will format the data coming from the server: if the field has datatype "date" and the user inputs "010304" then the input will be translated into "01.03.2004" (or other representation, dependent on date format settings). Please note: the datatype "float" is named a bit misleading - it represents any decimal format number. The server side representation may be a float value, but also can be a double or a BigDecimal property. | Optional | date float int long time timestamp color xs:decimal xs:double xs:date xs:dateTime xs:time ------------------------ N n.n P n.n string n L xs:boolean xs:byte xs:short
