JavaScript/jQuery TreeMap - title

The UI component's title is a short text that usually indicates what is visualized. If you need to specify the title's text only, assign it directly to the title property. Otherwise, set this property to an object with the text and other fields specified.

The title can be accompanied by a subtitle elaborating on the visualized subject using the title.subtitle object.

The following code sample illustrates how to set this property:

$(function() {
    $("#treeMapContainer").dxTreeMap({
        // ...
        title: {
            font: {
                color: "black"
            }
        }
    });
});

<dx-tree-map ... >
    <dxo-title ... >
        <dxo-font
            color="black">
        </dxo-font>
    </dxo-title>
</dx-tree-map>

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    // ...
}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxTreeMapModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxTreeMapModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }

<template>
    <DxTreeMap ... >
        <DxTitle ... >
            <DxFont
                color="black"
            />
        </DxTitle>
    </DxTreeMap>
</template>

<script>
import DxTreeMap, {
    DxTitle,
    DxFont
} from 'devextreme-vue/tree-map';

export default {
    components: {
        DxTreeMap,
        DxTitle,
        DxFont
    },
    // ...
}
</script>

import React from 'react';

import TreeMap, {
    Title,
    Font
} from 'devextreme-react/tree-map';

class App extends React.Component {
    render() {
        return (
            <TreeMap ... >
                <Title ... >
                    <Font color="black" />
                </Title>
            </TreeMap>
        );
    }
}
export default App;

@(Html.DevExtreme().TreeMap()
    // ...
    .Title(t => t
        .Font(f => f.Color("black"))
    )
)

Use the fields of this object to set the required values for the left, right, top and bottom title margins separately. If title margins suppose to be equal, assign a numeric value directly to the margin property.

If you need to specify the subtitle's text only, assign it directly to this property. Otherwise, set this property to an object with the text and other fields specified.

• title.horizontalAlignment

The following modes are available:

• "normal"
  Text breaks only at allowed breakpoints (for example, a space between two words).

• "breakWord"
  Words can be broken if there are no available breakpoints in the line.

• "none"
  Word wrap is disabled.

If the text overflows the container even after word wrap, the UI component applies the textOverflow property.
