Vector Plot Charts
Note: See our Vector Plot Gallery for inspiration on all the different vector plot possibilities.
Vector Chart Type and Options
ZingChart vector plots use the type
attribute and the options
object. In your chart object, add a type attribute and set the value to vectorplot
. Next, create an options object. Use the options
object to configure the vector plot data.
{
type: "vectorplot",
options: {}
Data
Vector plot charts use data added via a data
array inside of the options
object. Each sub-array in the data
array represents a vector that will be drawn on the chart. It is formatted in the following way: [xPosition, yPosition, length, angle]
.
{
type: "vectorplot",
"options": {
"data": [
[5, 5, 190, 18],
[5, 10, 185, 27],
[5, 15, 180, 36],
]
}
}
Chart-Specific Properties
Use the options
object to configure the vector plot and its arrows.
Arrow
The arrow
object allows you to control the minimum and maximum length and the style of the arrows. To style the arrows, use a style
object and the appropriate attributes, such as size
and backgroundColor
.
{
type: "vectorplot",
options: {
arrow: {
minLength: 12,
maxLength: 20,
style: {
size: 5,
backgroundColor: "yellow blue"
}
},
}
}
Further Customization
Configure your vector plot chart's appearance through value boxes, tooltips, and a legend.
Value Boxes
Value boxes are not visible on vector plot charts by default. To include them in your chart, add a valueBox
object to your plot
object. You can style and format them, as well as incorporate rules to force certain value boxes to show under certain conditions (e.g., to highlight outliers, notable data points, or minimum/maximum values).
Note: Learn more about value boxes with our Value Boxes Tutorial. For a list of available attributes, see our Value Boxes JSON Attributes/Syntax page.
In the example chart below, rules were used to display values greater than or equal to 90 and less than or equal to 10.
Note: Read more on rules and tokens in our Logic Rules and JavaScript Tokens tutorials.
{
plot: {
valueBox: {
rules: [
{
rule: "%v >= 90",
fontColor: "green"
},
{
rule: "%v >10 && %v < 90",
visible: false
},
{
rule: "%v <= 10",
fontColor: "blue"
}
]
}
},
}
Tooltips
Tooltips appear when you hover over a data point on your vector plot chart. To customize and style them, add a tooltip
object to your chart object. You can turn their visibility on or off with a visible
attribute. Set the value to true
(default) or false
.
Specify what text appears with a text
attribute. Place your desired text inside a string. ZingChart tokens, such as %v
(scale value) and %t
(plot text), can be used here. Style your tooltips (font, background, borders) with attributes such as fontColor
, fontFamily
, backgroundColor
, borderColor
, borderWidth
, and more.
Note: Learn more about tooltips with our Tooltips Tutorial. For more tooltip styling options, see our Tooltips JSON Attributes/Syntax page.
{
tooltip: {
text: "Arrow number %i: %v",
fontColor: "black",
fontFamily: "Georgia, serif",
backgroundColor: "white",
borderColor: "black",
borderWidth: 2
},
}
Legend
To include a legend on your chart, place a legend
object in your chart object. You can include attributes to specify your legend's layout, positioning, styling, headers/footers, and more.
{
type: "vectorplot",
legend: {}
}
Note: Learn more about legends with our Legends Tutorial and Legends JSON Attributes/Syntax page.
