This paper mainly introduces the core--option configuration object in Jqplot. At the same time, will also make a simple introduction to the various renderer of Jqplot.
This is mainly to refer to the Jqplot official website about option introduction and to knot their own simple practice and understanding of option related attributes to explain, if there is inappropriate or wrong place please correct me.

/************************jqplot the option object settings for each of the different plug-ins ******************************/
Barrenderer (Option object to set bar chart)
The option object is applicable to the configuration object settings associated with the series and Seriesdefault properties of the column graph
Seriesdefaults: {
Rendereroptions: {
Barpadding:8,//set distance between two bars of the same category (PX)
Barmargin:10,//Set distance (px) between two bars of different classification (same coordinate table point)

Cursor (cursor)
When the mouse is moved to the diagram, the mouse is displayed in the diagram, and is often used in conjunction with the highlighting function.
In addition, drill through a region of the diagram by setting the zoom-related property of the property (zoom in on the selected area)
This configuration object is configured directly under option
Cursor: {
Style: ' crosshair ',//When the mouse is moved to the picture, the mouse display style, the property value is the CSS class
Show:true,//whether to show the cursor
Showtooltip:true,//whether to display the prompt Information Bar
Followmouse:false,///cursor prompt Information Bar to move with cursor (mouse)
Tooltiplocation: ' SE ',///cursor Tip Information Bar position settings. If followmouse=true, then the location is
The position of the hint InfoBar relative to the cursor. Otherwise, the position of the cursor tip Information Bar in the icon
Optional value for this attribute: N, NE, E, se, etc.
Tooltipoffset:6,//hint info The position of the mouse (followmouse=true) or axis (Followmouse=false)
showtooltipgridposition:false,//whether to display the cursor position in the InfoBar (take the pixel distance from the left and top edge lines of the icon)
showtooltipunitposition:true,//whether to display the InfoBar where the prompt cursor is located (the data value on the vertical axis)

At the same time, the property also supports HTML format strings
Eg: ' <b><i><span style= ' color:red; >hello</span></i></b>%.2f '
},
Logaxisrenderer (exponential renderer)
The renderer has only two properties, and the exponential renderer is configured with Axesdefaults and axes configuration objects
Axesdefaults: {
Base:10,//index base
Tickdistribution: ' Even ',//Axis display mode: ' Even ' or ' power '. The ' even ' produces a uniform distribution of coordinates.
The value of the coordinate scale on the axis. and ' power ' determines the scale on the axis based on the increasing number of increases
},
Pierenderer (Option object to set pie chart)
Pie charts are configured with Seriesdefaults and series configuration objects
Seriesdefaults: {

}
},

Seriesdefaults: {
Pointlabels: {
Location: ' s ',//data label displayed near data point location
Ypadding:2//Data label distance from the data point in the direction of the longitudinal axis
}

Related Renderer Introduction
Copy Code code as follows:
1.dateAxisRenderer
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.dateaxisrenderer.min.js "/>
The renderer is primarily used to display the axis of the date format of the tick, which enhances the local data processing capabilities of JavaScript, which almost supports all date formats.
In addition, the renderer provides a powerful formatting feature that formats date strings in your data in the format you want and displays them on the axis tick marks.
2.categoryAxisRenderer
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.categoryaxisrenderer.min.js "/>
The renderer is used primarily to display the value displayed at the tick to the two tick marks, and of course its meaning changes, because the value at the tick value represents a value at a point, and it represents a range of values.
The renderer is better suited to use in conjunction with a bar chart.
3.barRenderer
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.barrenderer.min.js "/>
The renderer is primarily used to display a histogram, which controls the distance between each group (each category at a tick value) and the bar chart horizontally.
4.cursor
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.cursor.min.js "/
The renderer is mainly used when the mouse is moved to the diagram, the mouse is displayed in the figure, which is used in conjunction with the highlighting function.
Once the renderer-related reference package is referenced to the current page, the renderer takes effect immediately.
5.highlighter
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.highlighter.min.js "/>
The renderer is mainly used when the mouse is moved to the data points in the diagram, display the prompt bar near the mouse, and display relevant information in the Tip bar. The default display value is the vertical axis scale value. Of course, the information in the Cue box can be customized according to its own needs.
Once the renderer-related reference package is referenced to the current page, the renderer takes effect immediately.
6.logAxisRenderer
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.logaxisrenderer.min.js "/>
The renderer is used primarily to generate tick values on an axis in an exponential manner. By default, tick values are displayed evenly, but tick values can also be displayed exponentially.
7.ohlcRenderer
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.ohlcrenderer.min.js "/>
This renderer is primarily used to display Gantt charts. Typically, this shader is used with dateaxisrenderer more
8.dragable
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.dragable.min.js "/>
The renderer allows the user to drag a data point, and Jqplot automatically redraw the dragged new chart. Also, the data value of the dragged data point changes with the drag.
9.trendline
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.trendline.min.js "/>
The renderer is mainly used for linear regression calculation of existing data and automatically displays the result as a trendline, and when the user drags a data point, the trendline changes as the user drags.
10.pointLabels
Related Reference package: <script type= "Text/javascript" src= ". /plugins/jqplot.pointlabels.min.js "/>
The renderer is primarily used to label data node-related information in the vicinity of the data node, and its label is not displayed for the data that is empty.
