Matplotlibはtkinterの関数

Question

これは私の最初のpythonプロジェクトですので、この問題はちょっとばかばかしいかもしれません。
マンデルブローレンダラーを作成しようとしています。チュートリアルやコードからコードをまとめて、何かを作るために理解しているコードです。
基本的にレンダラー用のGUIのすべての数学と基本機能がありますが、matplotlibグラフを実際にtkinter GUI内にグラフ化することはできません。
matplolibの表示部分は実際には実行するにはmandelbrot_image(-0.8,-0.7,0,0.1,cmap='hot')が必要な機能です。そのコードが導入されている場合、マンデルブロセットはプロットされていますが、別のmatplotlibウィンドウに表示されます。

ここに私のコードがあります。私は事前に感謝してもう一度謝ります。

Answer 1

ここでの主な問題は、2つの異なる数字を作成することです。 Tkフレームに存在するものは、マンデルブロ画像を描くものではありません。
コード全体で同じ数字で作業する必要があります。
1つの方法は、mandelbrot_imageに図を作成させて戻し、後でFigureCanvasにそれを供給できるようにすることです。 完全な解決策については、以下を参照してください。

さらに、matplotlibにはfigshowメソッドがありません。おそらくimshow()が必要です。
