Draw graphs from columns of dataframe about dataframe-go HOT 9 CLOSED

1. Series string should have a function called ToFloat
2. You can add more series to []chart.Series{cs}
3. For plotting, everything is outsourced to the wcharczuk package, so you'll need to read it's docs

from dataframe-go.

1. Series string should have a function called ToFloat

My s (type: dataframe.Series) does not have this method

from dataframe-go.

or alternatively, when loading CSV data, use DictateDataType to configure the column as float64 so you will already have a SeriesFloat64.

from dataframe-go.

You also don't need to save plot to file. See readme on usage.

Ok, then. I understood conserning DictateDataType. This is not my case as I don't know the name of columns in advance. But I cannot still understand how to extract SeriesString form dataframe's columns which have type Series.

from dataframe-go.

you need to type assert

from dataframe-go.

I would really appreciate it if you could share a small example. Because this construction is not correct:

v := df.Series[2]
v1 := dataframe.NewSeriesString("name", nil, v)

I cannot imagine what should I do now.

Thanks for your assistance. Finally I was able to figure out the type assertions. Everything works now.
