google-visualization

问题 Recently I started working on Google Charts. Till now it is fine but now I am facing an issue with multiple selection. I am able to select multiple points by mouse clicks but I need to select range of points by dragging the mouse. Could you please help me in this? 回答1: using this answer to draw the selection range --> Select area/rectangle in javascript use chart method --> chart.getChartLayoutInterface().getBoundingBox() to find the bounds for each point... chart.getChartLayoutInterface()

问题 I have seen scripts that claim to enter coordinates and it'll tell you if they intersect, but I have an array of X,Y values for a couple of "lines" but how do I cycle through the points to find out if they intersect? I've included a photo of my graph and as you see, eventually my plots cross over, I just want to know if my values ever cross over (intersect). How do I run through this to find out if any intersection ever occurs? var Test = { x: [8043, 10695, 13292, 17163, 20716, 25270], y:

问题 In google charts, you can create a diffChart which will give you a nice representation of data by showing 1 series of data in front of the other, like so Problem is i need to do this with more then 2 series, i would like to do it with up to 4, stacking each item in front of each other. Is this possible using google charts?? I do not care if i have to use different google charts to accomplish this, but i need the 4 series in front of each other, NOT side by side Here is an example plunkr, but

问题 I am followinf the google Chart documentation for arrayToDataTable and the example states that I can use formatted values, like that: var data = google.visualization.arrayToDataTable([ ['Employee Name', 'Salary'], ['Mike', {v:22500, f:'18,500'}], ... where f:'18,500 is the formatted value to show. My code looks identical: var data = google.visualization.arrayToDataTable([ ['Category', 'Amount'], ['Food', {v:5595.819984, f:'5.595,82'}], ['Home', {v:1890.530002, f:'1.890,53'}], ['Mail', {v:8

问题 Is there a way to edit a google chart table cell?. I need to edit the cells at the 'Salary' column only. Then verify the new value it's not greater than the value at 'Max Salary' column. So far I been able only to get the row and column when clicked. This is the example code. google.load('visualization', '1', { packages: ['table'] }); google.setOnLoadCallback(drawTable); var row, col; function drawTable() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Name');

问题 I want to display some Data with googles Scatter Chart. No matter how I try I can't get the y axis labels to show. I tried various things, which were suggested here and on other forums. Including: Resizing the chart, resizing the label font, Rescaling the axis and changing the textPosition of the vAxis. None of this worked. The funny thing is that the ticks I defined are showing correctly placed gridlines. It is just the labels that are missing. The axis title is also displayed which leads me

问题 I have an undetermined number of data sets in a JSON feed. This means that I am never sure how many are coming back, it could be 1, 12 or 30, it's an unknown. The series are made up of a date and a value. I want to be able to draw a line chart with the multiple datasets. The datasets have different dates and times as well, to make things more complicated. I have the following code so far, that seems to create the google.visualization.DataTable() multiple times on the fly. success: function (d

问题 I am trying to figure ou the proper way to combine Puppeteer and the GoogleCharts library to render Bar charts and export a PNG image of the chart. The basic layout, mostly inspired by the Puppeteer documentation seems to be something like that, to create a new page with a canvas element. (async () => { const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.setContent(` <!DOCTYPE html> <html> <body> <canvas id="chart" width="580" height="400"></canvas> <
