Cannot read property split of null
I don't think there is a way to go back to -11_1 so I think -12 is the only option
I upgraded imagemagick to the latest version and am getting this error
(node:29179) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'split' of null at HTMLUnknownElement.getBBox (/mnt/c/Projects/cryptoBot/node_modules/anychart-nodejs/lib/anychart-node.js:155:29)
It seems in the getBBox function it's looking for a fontfamily and returning null. Any idea why this would be happening?
It is happening on char.draw() It is happening with many different example charts I've found for anycharts including the one on this repo It is still happening if I downgrade to 1.3.6
I have reformatted Ubuntu and it's happening on 16.04 and 18.04.
Here's my code just for sanity check. I'm just trying the example chart just to get it running
var jsdom = new JSDOM('<body><div id="container"></div></body>', {runScripts: 'dangerously'});
var window = jsdom.window;
const anychart = require('anychart')(window)
var chart = anychart.pie([
["Chocolate", 5],
["Rhubarb compote", 2],
["Crêpe Suzette", 2],
["American blueberry", 2],
["Buttermilk", 1]
]);
chart.title("Top 5 pancake fillings");
// set the container where chart will be drawn
chart.container("container");
// draw the chart on the page
chart.draw();
EDIT:
I have started using the 1.3.0-dev-preview-4 build for anycharts-nodejs and this error is gone. Only I am getting
Error: Stream yields empty buffer
at Socket.
@JacobCooley Thank you for your report! The problem comes with the update of AnyChart 8.4.0 As a temporary solution, you can downgrade your AnyChart npm module down to 8.3.0 version. Soon we will provide the fix for the AnyChart-NodeJS according to changes in AnyChart 8.4.0 library. I will notify you when the fix becomes available.
Great! The errors are gone! :D There's one issue now though, For png and jpg, my charts are generating, but my legend and labels are not.
Have any clue why this would be?
const yScale1 = anychart.scales.linear()
chart.yAxis(0).title("USD Price")
chart.yAxis(0).scale(yScale1)
const series1 = chart.line(formattedData)
series1.stroke('#00cc99')
series1.yScale(yScale1)
series1.name('USD Price')
chart.xAxis(0).labels().offsetX(25)
chart.xAxis(0).labels().width(100)
chart.xAxis(0).labels().format(function (){
let value = this.value
value = timeConverter(value, timeData)
return value
})
chart.yAxis(0).labels().format(function (){
return '$' + this.value
})
@JacobCooley Hm, this is strange behavior. We have been reported a similar problem, but it was solved. Probably we should check the required version of librsvg or other third-party libraries. I will investigate it and update you as I get results.
@JacobCooley Please, try the librsvg 2.44.8 version which is the latest. We made test and this version works properly. This should solve your issue!
I'm on linux, so I think the version numbers are a bit different because it says I'm up to date
It worked fine when I added anychart version 8.3.0 explicitly.
"dependencies": {
"anychart-nodejs": "^1.3.8",
"anychart": "8.3.0"
}
Issue still exists in latest version for anychart - 8.4.2
I had downloaded this module earlier on 23-09-2018 and npm version "anychart-nodejs": "^1.3.8" is working fine in the folder where npm_modules was synced on that day.
OS: Windows 10, 64 bit Node version 9.10.0
The same code does not work if I create new project with just one npm module dependency "anychart-nodejs": "^1.3.8" in package.json
"dependencies": {
"anychart-nodejs": "^1.3.8"
}
I get error as below:

@chandregowda This is a known issue which came with 8.4.0 update and later versions. We recommend using 8.3.0 version as a temporary workaround. We are working on the fix to solve this issue in 8.4* versions. As the fix becomes available we will update this issue.
I'm using v8.3.0 on OSX and deploying to Google Firebase Functions and I'm still receiving this issue, as well as a warning Warning! Please install rsvglib utility. (https://github.com/AnyChart/AnyChart-NodeJS).
I've already followed the instructions on the website and installed using
brew install imagemagick librsvg
@chuakc92
Please, check the installation of librsvg by brew list, this should library should in the list of installed formulas

@abhishekverma3189 Please, can you try to write PNG image of the chart using fs? Just like it is shown in the quick start article of the repo. Does it work in your environment?

@abhishekverma3189 Please, try to downgrade the Imagemagick to 7.0.8-11_1 version. The newer version leads to this error. The same problem was discussed in this issue.
I was able to get it working by using ImageMagick 7.0.7-39 and using "anychart-nodejs": "1.3.0-dev-preview-4",

@gansky-alexander The solution was provided above in this thread - https://github.com/AnyChart/AnyChart-NodeJS/issues/17#issuecomment-443569528
Same problem with :
"anychart": "^8.11.1",
"anychart-nodejs": "^1.3.8",
Error is :
/node_modules/anychart-nodejs/lib/anychart-node.js:155
var fontsArr = fontFamily.split(', ');
^
TypeError: Cannot read properties of null (reading 'split')
at HTMLUnknownElement.getBBox (/node_modules/anychart-nodejs/lib/anychart-node.js:155:29)
Can this please be fixed? downgrading anychart to 8.3.0 is not feasible for my project as it uses newer features of anychart like setting maximumGap on the stock charts.
