Change FontColor of title + axes / hide zero values

[keineAhnung667]

Hello mtatsuma,

Could you please add an option to change the FontColor of the title an the axes? Its gray by default. I changed it manually with Chart.defaults.global.defaultFontColor = this.config.color

And another thing: Could you add the ability to hide zero values in the rain chart? So if there is no rain, there is no text with "0" (Like here: https://stackoverflow.com/questions/58425747/how-to-hide-zero-data-value-from-chartjs)

Hi

Thank you for using the module.

I have dealt with the both requests. Please clone the module from the latest master branch and try it. To hide the zero label, you have to set showZeroRain config option as false.

NOTE: the latest master branch has some breaking changes because I bumped up Chart.js major version (v2.x -> v3.x).

Thanks for your effort. Im a little bit confused because in your Readme its written git clone -b v2.6.0 https://github.com/mtatsuma/MMM-WeatherChart.git

Can i update to the latest version (3.x) or do i have to wait?

[mtatsuma]

I was waiting for the chart.js datalabels plugin v2.0.0 to be released and it was released yesterday! https://github.com/chartjs/chartjs-plugin-datalabels/commit/b04395850bed5729e03e4adb150762819e85898b

Then, I will release v3.0.0 soon. Please give me a moment.

To install it, please try

git clone -b v3.0.0 https://github.com/mtatsuma/MMM-WeatherChart.git

Hi mtatsuma, I tried Version 3.0 now but there are some mistakes:

The text is cut and there are temperature labels missing.

My config:

    {
        module: "MMM-WeatherChart",
    //disabled: true,
        position: "top_right",
        config: {
            apiKey: "xyz",
            lat: 51.961563,
            lon: 7.628202,
            units: "metric",
            updateInterval: 60 * 60 * 1000, //60 min
            title: "Wetter Münster",
    fontSize: 20,
            showRain: true,
    showZeroRain: false,
    includeSnow: true,
            showIcon: false,
    iconWidth: 40,
    iconHeight: 40,
            fillColor: "rgba(30, 144, 255, 0.4)",
            dataNum: 13,
            dataType: "hourly",
    nightBorderDash: [5, 0],
            height: "300px",
            width: "600px",
        }
    },

Is my config wrong?

[mtatsuma]

I'm sorry for this late response and thank you for sharing your problem. I also reproduced the issue and I will fix that. Please give me some time.

[mtatsuma]

I have fixed the issue. Please clone the latest module

$ git clone https://github.com/mtatsuma/MMM-WeatherChart.git

and try it.

By the way, iconWidth and iconHeight in your config is no longer available from v3.0.0 because it does not work well for v3.x Chart.js.
