Foe example I would like to limit the width size. 回答1: As we already discussed here , to set a maximum width on every bar, we have to change either barGap or categoryGap accordingly, every time the scene or the chart are resized. The only difference from the refered question, is we have to resize the chart the first time is displayed. Based on the same code, let's create the setMaxBarWidth() method: private final NumberAxis

In previous Angular2 versions, I have been doing this well by using a 'chart.loader.ts' which has: export const { Chart } = require('chart.js'); Then in the component code I just import { Chart } from './chart.loader'; But after upgrading to cli 1.0.0 and Angular 4, I get the error: "Cannot find name 'require'". To reproduce the error: ng new newapp cd newapp npm install chart.js --save echo "export const { Chart } = require('chart.js');" >> src/app/chart.loader.ts ng serve In my 'tsconfig

That is performed by running a sleep on a background non-GUI thread and then upon waking up it runs a Platform.runLater to create the snapshot and image. Before the real 'action' for saving the image occurs we can see the window come up: While that image is rendering we have the background code that has been put to sleep by a Task . After 5000 millis that background task wakes up and launches a Platform.runLater to save the scene/pane/chart

However if the value of the bar is low enough, it ends up overlapping with the axis label (as shown by the purple bar). My first instinct was to set a max value and change the position of the data-label base on that. Something like, if value is less than $10 place the label outside just to the right of the bar. But there is a big problem with that approach. The size of the chart is variable and responsive, so that

Regular crosshair example out from API doesnt do this. If I set tooltip: { crosshairs: [true, true] } , it doesnt do what I need.

Code: $("#container").mousemove(move); var
