Курс очень чётко объясняет, когда использовать столбчатую диаграмму, а когда линейную или точечную, что раньше я делала почти наугад. Особенно понравился блок про то, как убрать лишние элементы с графика, чтобы главная мысль не терялась. После прохождения я по-другому смотрю на все отчёты, которые готовлю на работе.
Finalmente capisco quale grafico usare.
Понравилось, что упор сделан на выбор правильного типа графика под конкретные данные, а не просто на кнопки. После курса мои отчёты читаются как понятная история. Хотелось бы чуть больше примеров с большими наборами данных, но в целом очень полезно.
En çok zorlandığım konu hangi veriyi hangi grafikle göstereceğimi seçmekti, bu kurs tam o noktayı çözdü. Çizgi, sütun ve dağılım grafiklerini ne zaman kullanacağımı örneklerle öğrenmek çok aydınlatıcıydı. Artık raporlarımda gereksiz pasta grafikleri kullanmıyorum, bunun yerine veriyi bir hikaye gibi anlatmayı öğrendim. Sunum yaptığım toplantılarda insanlar sayıları çok daha hızlı anlıyor. Veriyle çalışan herkese içtenlikle öneririm.
データをただグラフにするだけでなく、伝えたい内容に応じてどのグラフを選ぶべきかを丁寧に説明してくれる講座でした。散布図と折れ線グラフの使い分けの部分が特に参考になりました。ただ、後半の応用的な事例がもう少し多いとさらに理解が深まったと思います。
Uzun zamandır hazırladığım raporlardaki grafiklerin neden etkili görünmediğini bir türlü çözemiyordum, bu kurs tam olarak o boşluğu doldurdu. Hangi veri için çubuk grafik, hangisi için çizgi ya da dağılım grafiği kullanılması gerektiği çok net örneklerle anlatılıyor. Renk kullanımı ve gereksiz görsel unsurları kaldırma kısmı özellikle işime yaradı, artık grafiklerim çok daha sade ve anlaşılır. Gerçek veri setleri üzerinden ilerlemek konuyu soyut kalmaktan kurtarıyor ve akılda kalıcı hale getiriyor. Kursu bitirdikten sonra elimdeki eski raporları tekrar gözden geçirip birçoğunu yeniden düzenledim. Veriyle çalışan herkesin gözden geçirmesi gereken pratik bir kurs oldu benim için.
Долго не могла понять, почему мои графики выглядят убедительно только для меня, а для остальных превращаются в кашу, и этот курс расставил всё по местам. Особенно полезной оказалась часть про выбор типа диаграммы под конкретную задачу — раньше я просто ставила столбчатую диаграмму на всё подряд. Примеры разбираются на реальных наборах данных, а не на абстрактных цифрах, что сильно помогает удержать внимание. Понравилось, как подробно объясняется работа с цветом и минимализмом, чтобы график не превращался в переливающийся хаос. После пары занятий я пересобрала несколько своих старых отчётов и разница видна невооружённым глазом. Однозначно один из немногих курсов, где теория сразу превращается в практический навык.
Berguna, tapi contohnya agak asas.
This course does a great job explaining the reasoning behind chart choices instead of just listing chart types, which is exactly what I needed. The section on decluttering visuals and cutting unnecessary gridlines and colors changed how I build every report now. I finally feel like my charts communicate a point instead of just displaying numbers.
Наконец перестала пихать круговые диаграммы повсюду, выбор графиков стал осознанным.
