Usage

statsgraph

import graspgraph as gg

statsgraph = gg.Statsgraph(
  gg.StatsgraphAxis([1, 2, 3, 4, 5]),
  gg.StatsgraphAxis([11, 12, 13, 14, 15]),
  gg.FigureColors(line = "blue"))
figure = statsgraph.to_figure()
figure.LayoutTitleText = "<b>[statsgraph]<br>タイトル</b>"
figure.XTitleText = "X軸"
figure.YTitleText = "Y軸"
figure.Write("./statsgraph.png")

dbergraph

import graspgraph as gg

prefix = "./database"
dbergraph = gg.Dbergraph(gg.Database.from_file_path(gg.Path.join(prefix, "yaml")))
dbergraph.Database.update()
dot = dbergraph.to_dot()
dot.TitleText = "<b>[dbergraph]</b>"
pdfFilePath = gg.Path.join(prefix, "pdf")
pngFilePath = gg.Path.join(prefix, "png")
dot.Write(pdfFilePath)
gg.Pdf.convert(pdfFilePath, pngFilePath)

pivotgraph

import graspgraph as gg

pivotTable = gg.PivotTable.from_array([
  ["", "収入", "支出", "利益"],
  ["1月", 1, 2, 3],
  ["2月", -1, -2.5, -2],
  ["3月", 0, -0.5, 1],
])
pivotgraph = gg.Pivotgraph(gg.PivotgraphAxis(pivotTable, gg.FigureTick(2)), gg.PivotgraphColors(bars = ["blue", "red", "green"]))
figure = pivotgraph.to_figure()
figure.LayoutTitleText = "<b>[pivotgraph]</b>"
figure.XTitleText = "金額(百万円)"
figure.YTitleText = "月次"
figure.Write("./images/pivot/usage.png")

CLI

pdf.convert

Convert PDF to image

1. Image(PNG) conversion by CLI execution

pdf.convert # <pdf file path> <image file path>

graspgraph pdf.convert graph.pdf graph.png

graph.png is done.
